Get out your agenda if you see your name below. I would like to have you in my FLEX Wednesday.
Determine whether the following polygons are similar.
How do I graph dilations on a coordinate plane?
Dilation– the image produced by enlarging or reducing a figure
Center– a fixed point used for measurement when altering the size of an image
How do I find the coordinates for a new, dilated figure?
Complete the following table by substituting the scale factor for the variable, a.
hint: just multiply all of the coordinates by the scale factor
How do I find and classify a scale factor?
Write a ratio of the x or y-coordinate of one vertex of the dilation (NEW figure) to the x or y-coordinate of the original (OLD) figure.
The Scale Factor is 3
If the scale factor is greater than one the dilation is and ENLARGEMENT
If the scale factor is less than one the dilation is a REDUCTION
